As part of the first 6 of 12 books in damage control training is routine. There are also electronics on the superstructure that constantly take air samples to detect the chemical, biological, and nuclear readings. I know this since I did planned maintenance on such.

Agreed. I was on carriers from 1985 to 1990 and was in a repair locker for nearly three years of that. We drilled for a nuclear blast scenario as part of our training. I was onboard the USS Theodore Roosevelt (CVN-71) when they did the nuclear blast simulation testings in 87 (or 88?). They did four explosive tests simulating different nuclear explosions from different distances. I was in a repair locker during all four tests. The first test was barely noticeable. The next two got our attention, but wasn't anything worrisome. But the forth test was a completely different experience. Even though we were warned to brace and taught how to stand (holding onto a wall without our knees bent and on the balls of our feet) the force of the blast was significant. The entire carrier moved sideways over a foot instantaneously. There was some damage and a couple small fires on board. Nothing was damaged in my repair locker area. We spent several hours going through our entire area looking for burst pipes, fires, etc., but we found nothing in our designated repair locker area. It was an experience. If you look on the web (or maybe even KZbin) you can find photos of the CVN-71 nuclear bomb testing. The explosion from the fourth test was about quarter mile from the ship and as big as the carrier itself.

I wonder if it's possible with modern computers to release and trigger torpedoes close enough to the ship and at the right time to create a proper water wall against that initial blast and heat wave?

[@Mike5Brown]

I’m actually surprised I didn’t know this one. I did a fair bit of reading about these tests. It is surprising how “resistive” ships actually are against nukes or maybe a better way of phrasing it is how quickly damage from a nuclear blast dissipates with range. I saw a few things that basically implied that enhanced radiation (neutron bomb) to kill the crew was a “better” option than standard nuke (blast focused). Not that a standard nuke isn’t going to deliver enough to kill the crew.

[@josephburchanowski4636]

I don't think a neutron bomb would be that effective against ships. The high humidity of the air reduces range of neutron radiation, and the large amount of metal on the ship still provides some shielding. The lethal range of radiation from the neutron bomb might even be less than its lethal blast range. Such became the case for tanks that were hardened against radiation. If it is the case for tanks, I'd image that it would also be the case for ships. It would probably be better to get a close detonation with a conventional tactical nuke, than to use an enhance radiation bomb. Or just use a nuclear torpedo, naval mine, or self destructing unmanned submarine.

[@Odunam]

As a side point, nukes being less effective against ships at sea is not that surprising as their main source of damage is the fires they start. In Hiroshima, a 15 Kt bomb caused a 200 m radius fireball with a dangerous blast zone extending ~1000 m; the fires extended to 2000 m. In area terms, 12 km² of the city was destroyed : 1% by the fireball, 25% by the blast, 74% by the fires started by the heat.

[@thomasschulz2167]

@@Odunam A near surface or above ground detonation would be less effective. However in the case of a torpedo or mine maybe even a shell, the the goal would be to generate a bubble of less dense water or a cavity under a ship or several. The cavitation would cause significant hydrostatic shock effects if not just out right dropping a relatively small ship into a couple hundred meter deep hole. The Navy knew that the loss of a ship was a forgone conclusion in the case of a deep water detonation. They were more interested in figuring out how to protect the rest of the taskforce that may have survived.

[@DanielBrown-sn9op]

Many in power who believed that things are more important than people loved the concept of a neutron bomb.😣

[@OOTurok]

That's not the purpose of a nuetron bomb. Neutron bombs were NOT considered a "better" option, because the blast range of standard nukes dissipated too quickly. The damage from neutron bombs have much smaller blast radiuses than standard nukes, & they are purposely designed that way. The concept behind neutron bombs, & their purpose, is to kill the population, while leaving cities intact... by using a very low yield nuclear weapon, to minimize the physical power of the blast, while emitting extremely high yield neutron radiation. Essentially, neutron bombs are meant to be air blasted over cities, far enough away, that the physical blast does not reach the target, & shower the population with neutron radiation which, break up DNA molecules & cell membranes, literally turning organic tissues into goo.

[@jickhertz4124]

I think it also helps reduce the impact of heat (as it vaporises the mist instead of the deck) and the impact of the blast (as it dissipates the KE). Nice vid!

[@barnmaddo]

From everything I've read, if you're close enough for the heat to be a problem, then the blastwave was already going to kill you anyways.

One of the ships present was the battleship Arkansas, she rode out test Able (the airburst) with minimal damage, but was very close to ground zero for test baker: The 26,000 ton battleship was bodily lifted from the sea as all the water in the lagoon was instantly vaporised or blasted away at mach 2. The blast removed everything above deck and completely impacted the starboard side of her hull. It also ripped off the two starboard propellers and their shafts, along with the rudder and part of the stern, shortening the hull by 7metres. The poor ship was then hammered down into the shallow bottom by the descent of the approximately two million tons of spray and seabed thrown up by the blast. This sank Arkansas.

While this system was designed for the cold war, it's actually quite useful as an IR signature reduction technique. Additionally some ships also use an additional measure by pressuring the citadel (cabin of the ship) to 2 Atms or higher to prevent further ingress of NBCs.

​@@pyrotechnicalbirdman5356 Not everyone starts counting pressure from an absolute vacuum. Its often a lot more practical to zero things to 1 atmosphere. For example, do you pump your car tires up to around 35 psi or 50? So, when talking about a part of a ship getting pressurized to 2 psi, a reasonable person would interpret that as *adding* 2 psi of overpressure, rather than pulling 12.7psi of vacuum.

@@dgthe3 The OP says: "pressuring the citadel (cabin of the ship) to 2 Atms or higher to prevent further ingress of NBCs." The next response says "i think you mean 2 psi."

No layperson is going to any bullshit calculations to arrive at the figure you desire, they will use the unit of measurement provided.

In 1992 I was on the USS Ticonderoga CG-47 in the Persian Gulf doing '7 knot circles to nowhere'. I went out at about sunset to sit on the chaff lockers and write a letter home. About 10 minutes into this, I noticed a trickle of water coming from the counter-measure washdown nozzles on the 03 level above my head. Not uncommon as the ship rocked gently at sea. Didn't give it another thought. About 10 seconds later, the entire ship was suddenly being rinsed. It was loud and I probably peed a little. Masses of water. Everywhere.

It was a fun day at sea testing them as we ran around in our swim gear. It is not just press a button and it happens there are several valves that need to be opened to put the system online. Add to that, if it were "necessary" to do an Unscheduled washdown the ship would go to GENERAL QUARTERS! Word would be passed alerting the crew in charge of washdown system to open the valves needed.

"Clouds of (water)vapor" are always 100% transparent, you can't see them. When the vapour condenses into droplets, it forms a cloud which you can see. When those droplets evaporate and turn back into vapour again, you can no longer see them. The water doesn't move (much), it is the local availability of energy that changes. From above the dew-point to below and back again. Your example of the .50BMG confuses me a bit. a) There are much better examples of this phenomenon. F18 Hornet with a conical cloud formed around its fuselage, for one. b) Old school camera's were used to photograph these things. It is amazing to see how these worked.... c) Are you describing the exact opposite regarding the .50BMG than what you state in your first sentence? Where clouds disappear and then re-appear when a .50BMG passes by? Bonus info: You've probably seen con-trails behind aeroplanes at altitude. Have you ever seen the opposite? When a big aeroplane is flying slightly above or within a thin cloud, the heat from the exhaust will locally evaporate the thin cloud, making it transparent. It is a rare phenomenon. In stead of a blue sky with a white stripe in it, you get a white sky with a blue stripe in it.

*Correction:* The yeild rating in Kilotons and Megatons have to do with the amount of energy the weapon can generate through over-pressure if detonated at 2500ft above sea level. There is a drastic difference in the actual kind of energy between TNT, a high explosive that contains its charge mass, and Nuclear Fission/Fusion which does NOT contain a charge mass. When detonated in water or in the ground the Fission and Fusion devices actually have lower effective yeilds, underground drastically so. In space a 20MT Nuclear Fission weapon will have less force than a 17KT TNT charge because there is NOTHING for the space detonated weapon to expand to produce a shock wave. In spite of the moronic news this year about using Nuclear weapons to protect Earth from asteroids... we cannot do so because the mass of the object will still strike the Earth but will not only be spread out it will also be highly radioactive.

[@jannikheidemann3805]

What I think it is after watching the intro: A water deluge system to absorb the thermal radiation so that the metal hull doesn't suddenly expand thermaly and cracks. Aditionaly it might protect a little by making the air around the ships heavier and therefore diverting the shockwaves somewhat along a path through the medium with less mass.

[@whirledpeaz5758]

Correct.

Can the washdown system be used to reduce the infrared signature of a vessel?

[@jaredfromtheemupen7990]

Asking the real questions

[@DreadX10]

Yes, that is why we don't hunt for subs with infrared detectors. Subs have taken this pre-wetting to the extreme.....

[@WilliamRoyNelson]

I don' think Infrared is a big thing for naval detection, although I could be wrong. Infrared requires line of sight, and on the ocean there's not much to hide behind if you're within visual range (about 5km). Reducing magnetic, electromagnetic and radar signatures are much more important.

[@DreadX10]

@@WilliamRoyNelson Warships have IR-decoys (flares) on board. So it is a concern. When the sun is low in the sky, it gives you something to hide in front off (for about an hour). Weird, isn't it? Visual range is a lot more than 5 km. Typically 25-30 km for sensors on top of the superstructure. Having a low magnetic signature helps against magnetic mines and ships are de-Gauss-ed for this reason (not 100% effective). Leaves, EM in general and that is so important, they changed the design of the ships (for RADAR) and set up an EMCON plan to restrict EM emissions.

[@WilliamRoyNelson]

@@DreadX10 I totally forgot that SRBOC can fire infrared decoys as well as chaff. And of course the other thing I overlooked is that 5km isn't going to apply to someone above sea level. I'm going to downgrade my answer to "ehh, maybe."

[@stephendoherty8291]

Also a useful fire supression system in the event of a serious fire, which might stop the fire or allow more time to mitigate/abandon ship without so much haste. It might also provide time for longer weapon use while such weapons/guns can still be used with any effectiveness.

[@billotto602]

What will happen if the nuclear reactor in aircraft carrier is blasted with a nuclear bomb?

[@zzirSnipzz1]

Nuclear contaminates will leak out most likely if its ever breached, if they manage to hit enough to stop water getting to the reactor you will get a steam explosion like the Chernobyl recator

[@Joshnaks]

The answer is probably not what you think.

[@ThereelOfficial]

It would more than likely vaporize the reactor and spread nuclear material pretty far, though it depends on the yield.

[@PhilJonesIII]

The crap that didn't fall on the ships, fell into the ocean anyway. You can take some small comfort in the fact that most living things in the water, around the blast, were already dead from compression/heat. They knew all this before testing began, but, 'that's the price of freedom', they say. Who knows how many species of marine life were simply erased during the 2000+ tests by various nations?

[@glrasshopper]

@@PhilJonesIII Speaking as someone whom lives in the South Pacific, and thus is reliant of the health of the ocean, this type of thinking is what is killing our planet. Having such a system only makes the US Navy more blasé about where they place these floating targets.

[@PhilJonesIII]

@@glrasshopper I was being very sarcastic. No way do I condone this type of testing. Those tests killed a lot of innocent people, many just going about their business. The tests continue to render a lot of places uninhabitable. I have no expectation of any official report admitting fully to the extent of the damage. As for the marine/wildlife, they might as well have said: "Let's find one of the most beautiful and diverse places on the planet and destroy it."

[@protesialbanese]

In italian is called "cortina di abbattimento" meaning "suppressing curtain", and many civil industrial facilities use them (eg. chemical plants) dousing water or even reagents to mitigate the spreading of an intended dangerous chemical. This is one of the last layer of contingency, and when deployed it means that a disaster Is already under way.
